West College Pond No. 1 Divider Levee

Services

Client

City of Santa Rosa

Location

Santa Rosa, CA

Scope of Work

New Divider Levee within the Existing West College Pond No. 1 allowing storage of recycled water on one side and high flow wastewater storage on the other. Recycled water storage at the West College Facility is a critical element in controlling suction side hydraulics for pumping stations on the City of Santa Rosa Urban Reuse water recycling system.

Project Challenges

Eliminate difficulties associated with operation of the pond in a dual-purpose fashion.

Determine optimal layout for levee to provide easy access and maintain gravity drainage for both ponds.

Solutions and Successes

Project complete within one year.

Increased usable depth in recycled water pond with new connection to pump station wet well.

Identified and capped sand channels within the bottom of the high flow storage pond, likely due to an old stream remnant, to eliminate a potential path for seepage.

Other notes of interest

Project included installation of 1,500 feet of 48-inch recycled water pipe, 450 feet of stormwater force main piping, over 27,500 cubic yards of grading, riprap rock slope protection, new pump station wet well connection.
